If the churchill gets nerfed too much, I don't think people are gonna build either of the final two brit tanks. Hammer and anvil will come down to a choice between the perks and everyone will ignore the vehicles
Doomsday prophet here bois.
No one is saying to "nerf too much" churchills, and what is "too much" for you?
It doesnt need a genius to realize that an onvernerfed unit wont be used, but maybe a fair nerf will make churchills be used as much as other factions can play aswell
As it is, very few players pick hammer instead of anvil. And comets are never taken into balance issues since they are not being used (it cant be UP, if it absent from games!).
People did complaint rightfully about KT being a "I WIN" button, but if chruchulls are to become the UKF most important unit, no one bats an eye?
If they get limited to 1, then shouldn't they get buffed with a large price increase? At least feels like the comet in it's current state isn't good enough to limit, and if you nerf the Churchill same for it IMO. Might be good enough now to limit, idk
Cost efficiency for premium units is a very bad idea, there is not a single other unit that does that, neither allied or axis. And cuhrchuills perk is durability and field presence.
So Remove smoke, slap infantry buff aura. Increase frontal armor, reduce some rear armor and decrease its HP pool to make it risky but only to RNG to throw them into the frontlines. Maybe add a unique feature against snaring (an active ability that allows them to move at full speed no matter if they have engine crit).
Those changes will give a high risk/high reward/high skill profile to churchills
